On a recent Friday, the three-story high, cream-colored mosque bustled with activity.

About 200 men crowded the crimson carpet in the main hall as Imam Abdelkhaliq El-Nerib led prayers from a gold-painted pulpit at the front of the room. Wall hangings with Arabic script and geometric patterns hung on either side of the pulpit. Dozens more worshippers knelt on a blue tarp spread outside. The mosque has two services on Fridays to accommodate the large congregation.

"We're not committing a crime, so of course we take issue with them spying on our people just because they're praying in the mosque," El Nerib said through a translator. "To track people who are frequent visitors to the mosque simply because they are coming to the mosque negates the freedom of religion that is a fundamental right enshrined in this country's Constitution."

Members of the mosque pointed out errors in the police document. The address, for instance, is wrong. And though the document says Chechens attended the mosque, worshippers said they had never heard of any. Most attendees are Palestinian, said El-Nerib, who's Egyptian.

El-Nerib said he has a good relationship with local police. He, like others interviewed at the mosque, said they have nothing to hide.

"Whether it's in public or private, we say the same thing: We are loyal American citizens," El-Nerib said. "We are part and parcel of this society. We have lived here, we have found nothing but safety and security and protection of our rights."
